Application September 26, 1944, Serial'No; 555,801;

Our invention relates to a lampstructureprovided with support meansarticulatelysecured thereto permitting hanging; as well as angular adjustment on a supporting. body or horizontal positioning of the headlamp structure proper.

An important object of our invention is to provide a head lamp structure of the aforementioned character in which the adjustable positioning means can be compactlycollapsed permitting the said lamp structure to be seated within a housing having a concave seating support therefore.

Another object of our invention is to provide a lamp having articulately, secured thereto positioning means comprised of... a substantially formed U- shaped structure to which is articulately secured a V-shaped structure and an I-shaped structure secured to the said V-shaped structure, affording various angular positions for setting up the said head lamp-structure in all positions within a range of 90 from the vertical to the horizontal position, and as well permitting hanging of the saidhead lamp structure whenever that method of supportshould be desired.

Another object of our invention is the pro- Vision of a head lamp structure provided with adjustable positioning means which is practical in its construction, useful and efficient in its operation, and of such elemental structure as to warrant economical manufacture thereof in quantity production.

Other features, objects and advantages inherent in our invention will become apparent from an examination of the accompanying drawings, when looked upon in the light of the ensuing description, having special reference to the elemental structure designated by numerical symbols corresponding in all views, and in which:

Fig. l is a side view of our invention showing the varied angular adjustment in which it may be positioned on a supporting body.

Fig. 2 is a front view of the positioning means secured to the lamp structure when the said positioning means is in collapsed form.

Fig. 3 is a top view of our invention showing how the same may be compactly retained within seating means provided in a holder adapted to vreceive the same when in inoperative position.

Fig. l is a perspective view showing how the supporting means may be adjustably set up in order to maintain the head light structure in a horizontal position casting the beams or rays of light in an upward direction.

Fig. 5 indicates how the positioning means may be utilized for hanging purposes when it is de- 2 Claims. (01. 240-53) 2. sired to suspendithe head light structure comprising our invention.

Referring to the .various figures, 6 generally,

designates the lamp structure comprisinglourinvention which is madeup of a hemispherical casing and provided with a tubularextfension 'l to which is secured the electrical wire connection 8 providing suitable terminals for contacting an electrical bulb 24 which maybe interchangeably, and'removably positioned within the said tubular,

socket "l.

The hemispherical section 9 of the head light structure may be suitably polished to act as a reflecting. surface and thus concentrate the rays of light emanating from. the light source or bulb 24.. The hemispherical section 9 is provided with two ears. or lugs lil having bearing portions 22 adapted to receive the positioningmeans generally designated II, which is, preferably, made of awirestructure and iscomprised of a U -shaped element [2 having right angularly extended,

therefrom short projections. or. trunnions I? which ,may be sprung into and articulately. securedto the bearing portions 22 of the lugs Ill so as to articulate freely therein and serve as an angular positioning means for the lamp as indicated by the full and dotted lines of Figure 1.

To the U-shaped structure 12 we attach a V-shaped wire structure 14 which is adapted to be articulately secured by virtue of the loop pOrtions l5 to the base 25 of the structure [2 in order to operate articulately thereon. To the crotch portion 26 of the V element I4 we secure a rod or lever structure [6 which has a loop portion I! articulately secured to the crotch portion 28 of the V element I4.

The free end of the lever element I6 is provided with a semi-circular notch portion l8 adapted to receive the foot portion 21 of the head light structure 6. The lamp 6 or head light structure 6 is adapted to be located when in inoperative position within the socket IQ of the housing element 20, which is also provided with a slotted portion 2i in order to permit the wire element 8 to travel back and forth on a reel structure which may be positioned within the housing 20 as indicated in our prior patent No. 2,424,719, issued July 29, 1947, of which this application is a continuation-in-part.

In Figure 4, we indicate how the support means generally designated l I may be arranged to support our head light 6 in a horizontal position casting the beam of light directly upward. By swinging the supports I4 and I6 to the rear of the support 12 as positioned in that view, the head light structure may be positioned also in a horizontal position by having its beams of light directed downward on th supporting body 28. Occasionally, such a setting may be required when for close examination of parts, especially, if repairs or such examination is to be made under artificial light.

In Figure 5, we indicate how our invention by virtue of its articulate supporting means Il may be hung for purposes of throwing its beam of light at a certain height or level to aid in certain operations, especially if the arrangement is utilized in connection with an automobile or other similar machines. The collapsed positioning means I I may serve the purpose of attachment for hanging on a hook 23 as indicated in Figure 5.

Thus it can be seen that we have provided a head lamp structure which has unusual and novel means for positioning the same angularly within a radius of substantially 90, and permitting horizontal position for casting beams directly upward or in the inverse relation thereto, and that is to cast the beams of light downward on a supporting body.

Altho we have, herein, indicated and disclosed a preferred form of our invention, we reserve the right to all modifications and improvements coming within the scope and spirit of our invention, the same to be limited only by the appended claims.

Having thus described and revealed our invention whatwe claim as novel and desire to secure by Letters Patent, is:

1. In a portable light device, a lamp casing provided with two supporting lugs and a foot element oppositely disposed to the said supporting lugs, and angular positioning means comprising, a U-shaped wire element provided with trunnions articulately secured to the said supporting lugs, a V-shaped wire element of smaller dimension than the said U-shaped element and having its free ends articulately secured to the base of the said U-shaped wire element, and a rod supporting element of smaller dimension than the said V shaped element articulately secured to the crotch portion of the said V-shaped wire element, the said rod supporting element being provided with a notched formation at its free end adapted to retain releasably the said foot element.

2. In a portable light device, a lamp casing provided with two supporting lugs and a foot element oppositely disposed to the said supporting lugs, and angular positioning means comprising, a U-shaped wire element provided with trunnions articulately secured to the said supporting lugs, a V-shaped wire element of smaller dimension than the said U-shaped element and having its free ends articulately secured to the base of the said U-shaped wire element, and a rod supporting element of smaller dimension than the said vshaped element articulately secured to the crotch portion of the said V-shaped wire element, the said rod supporting element being provided with a notched formation at its free end adapted to retain releasably the said foot element, the said V-shaped wire element and the said rod supporting element being constructed and arranged to collapse Within the plane of the said U-shaped wire element.
